On online shopping platforms, consumers may deliberately damage the reputation of merchants in a variety of ways, including but not limited to the following: 1. **False negative reviews**: Posting false negative reviews, exaggerating or fabricating issues such as product quality and service attitude, and influencing other consumers' purchasing decisions. 2. **Group attacks**: Mobilizing multiple people to post negative reviews of a merchant at the same time to create the illusion that the merchant has a bad reputation. 3. **Malicious returns/refunds**: Deliberately making false reasons to request returns or refunds after purchasing goods, causing economic losses and credit impact to merchants. 4. **Misleading reviews**: Deliberately providing wrong information or confusing the public in reviews, causing other consumers to misunderstand the goods or services. 5. **Ambiguous reviews**: Using ambiguous or double-meaning reviews to bias readers' views of merchants. 6. **Suggesting that competitors are better**: Recommending competitors' goods or services in comments by implicit or direct comparison. 7. **Complaining to the platform**: Frequently complaining to e-commerce platforms about merchants, trying to get the platform to punish or demote the merchants. 8. **Emotional manipulation**: Sharing exciting or tragic personal stories to bias the public against merchants. 9. **Impersonating other users**: Creating multiple accounts or using someone else's identity to repeatedly post negative reviews to create the illusion of poor credibility. These behaviors not only damage the reputation of merchants, but may also have a negative impact on the entire market environment. Most e-commerce platforms will take measures to prevent and punish such behaviors to maintain a fair and just market environment.
